In elderly patients with few remaining teeth, overdenture is a good treatment option. Roots beneath the denture protect the alveolar ridge, offer proprioception and improve retention, stability and masticatory efficiency of dentures. Customization of attachments available is a viable alternative for some patients in which prefabricated attachments cannot be placed or in which cost is a factor; to improve the final outcome of the treatment. Due to competitive commercialization, implant treatment has become the norm in current dentistry and the concept of tooth supported overdentures has eclipsed, but with proper case selection, thorough treatment planning and modifications in the denture such as customization of attachments, amalgam stops, cross-linked teeth, and metallic mesh can be applied to prolong the longevity and success of the attachment overdenture prosthesis.
在余留牙较少的老年患者中，覆盖义齿是一种很好的治疗选择。义齿下方的牙根可保护牙槽嵴，提供本体感觉，并提高义齿的固位、稳定和咀嚼效率。对于一些无法放置预制附着体或成本是一个因素的患者，定制附着体是一种可行的选择；以改善治疗的最终效果。由于商业化竞争，种植治疗已成为当前牙科的常态，牙支持式覆盖义齿的概念已黯然失色，但通过适当的病例选择、全面的治疗计划以及义齿的改良，如定制附着体、汞合金阻挡块、交联牙和金属网，可以延长附着体覆盖义齿修复体的使用寿命并提高成功率。
